insert into k_v_test (temp,key_,value_) values('temp','年龄','')

insert into k_v_test (temp,key_,value_) values('temp','性别','男')

insert into k_v_test (temp,key_,value_) values('temp','生日','1986-')

insert into k_v_test (temp,key_,value_) values('temp','姓名','张某')

insert into k_v_test (temp,key_,value_) values('temp','手机','')

go

select * from k_v_test

然后执行下看到的中文都会变成'?'。。。。

然后搜了下...

说是在insert的时候,当字符是中文的时候在前面加上'N'就可以了...

果然...

例如:

insert into k_v_test (temp,key_,value_) values('temp',N'年龄','')

use string007

if exists (select 1

            from  sysobjects

           where  id = object_id('K_V_TEST')

            and   type = 'U')

   drop table K_V_TEST

go

create table K_V_TEST (

    temp                varchar(100)        not null,

   autoid               int                  identity,

   key_                 nvarchar(400)         not null,

   value_               nvarchar(200)         not null,

   constraint PK_K_V_TEST primary key (autoid)

)

go

insert into k_v_test (temp,key_,value_) values('temp','key','value')

insert into k_v_test (temp,key_,value_) values('temp',N'年龄','')

insert into k_v_test (temp,key_,value_) values('temp',N'性别',N'男')

insert into k_v_test (temp,key_,value_) values('temp',N'生日','1986-')

insert into k_v_test (temp,key_,value_) values('temp',N'姓名',N'张某')

insert into k_v_test (temp,key_,value_) values('temp',N'手机','')

go

select * from k_v_test
